About this study

Official title: Phase 2, Placebo-Controlled, Parallel Group Dose-Finding Study to Evaluate the Efficacy and Safety of Three Dose Levels of AD036 in Adults With Obstructive Sleep Apnea

This is a randomized, double blind, placebo-controlled, repeat-dose, parallel arm, outpatient and inpatient phase 2 clinical study to examine the efficacy and safety of three dose levels of AD036 versus placebo in patients with obstructive sleep apnea.

Read the detailed description

This was a randomized, double-blind, placebo-controlled, repeat-dose, parallel arm, outpatient and inpatient, multicenter, dose-finding study of the combination of atomoxetine and oxybutynin in adults with OSA documented by polysomnography (PSG).

Approximately 140 subjects were to be randomized 1:1:1:1 to receive 1 of 3 different fixed-dose combinations of oxybutynin and atomoxetine or matching placebo.

For all subjects, the study consisted of:

  • A screening and baseline period in which subjects' eligibility was determined
  • An initial 2-night, at-home blinded baseline period in which all subjects received placebo
  • A 3-night, run-in period in which subjects received:
  • Low-dose combination for subjects randomized to one of the 3 study treatment arms
  • Placebo for subjects randomized to the placebo treatment arm
  • A 7-night treatment period in which subjects received the treatment to which they were randomized, i.e., 1 of the 3 different fixed-dose combinations of drugs, or placebo
  • An end of study visit

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Apnea Hypopnea Index (AHI)

    Number of participants with ≥50% reduction in apnea hypopnea index (AHI). AHI is the average number of apneas and hypopneas a person experiences each hour during sleep, to register as an event an apnea or hypopnea must last at least 10 seconds or longer. To measure this, doctors divide the total number of apneic and hypopneic events by the total number of hours the person was asleep.

    Measured: 10 days

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing AD036 Dose 1, AD036 Dose 2 and AD036 Dose 3 in people with Obstructive Sleep Apnea, run by Apnimed at 12 sites in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 3 inclusion and 17 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 17 Jan 2023. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 12 sites in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 17 Jan 2023). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Apnea Hypopnea Index (AHI) (time frame: 10 days). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 17 Jan 2023.
